Thanks Alan, I checked /etc/fstab and the file system was not mounted 
with user_xattr option.
I did remount and it worked fine.
[root at XXX]# mount -o remount,user_xattr /
[root at XXX]# exit
bash-3.00$ ./jdk1.7.0/bin/java Test .
supports DosFileAttributeView ?? true
is hidden false

Alan, Can you please explain above stated fact "Samba stores DOS 
attributes as an extended (named) attribute.".
When do we use DosFileAttributes in Linux and Solaris? Do we use it on 
smbfs file system?
